That's absurd. Netflix would sooner stop supporting web browsers on desktop OS's before they started allowing DRM-free streaming. Regardless of your own view on DRM, Netflix's licenses to the content they provide almost certainly requires the use of DRM, and the companies that own the content would never be willing to relicense them for DRM-free streaming.
Without EME, Netflix would be relying on proprietary browser plugins forever, and if a platform with a significant userbase appeared that didn't support any form of proprietary plugin, and they wanted to support that platform, they'd develop their own proprietary application for it instead of providing DRM-free streaming (think of how Netflix has applications for mobile OS's and even consoles, both living room consoles and handheld consoles).
